Something y'all may want to think about. Let's assume that 590 fixes the signal and they are hearable...most everywhere. Now if it works here, what would stop them from attempting it in other markets (where possible, of course).
Next, since the stations all run THE SAME PROGRAMMING and appeal to the SAME AUDIENCE and let's, for the sake of argument, say that with PPM entering the picture the ratings explode or, at best, increase moderately. This is a national format where all, or just about all of the entity is taken care of at one or two centralized locations. They make their money, have one of the lowest overheads in the industry and...
...let's suppose Clear Channel, Citadel, CBS, etc. decide to centralize their operations. No local sales force, no local traffic to schedule, no local announcers to pay, no voicetracking, all satellite all the time, all over the country. Imagine leaving for a trip from Atlanta and listening to your favorite show while driving to Ohio.
For those who want radio to be what it once was, it has the potential to become everything it was never intended to be. For those who are only in it for the money, you may be looking at a gold mine...or a death knell. Either way, the implications are staggering. (By the way, I know I left a bunch of stuff out but I just wanted to get the point across...radio as we have known it HAS changed. We can either change with it or be destroyed by it.
